SCI Decoding - Script structure

# Script structure

This is the structure for an unencoded script file, you can extract a script file from the `RESOURCE.*` files with the SCI Decoder disponible on Baf's page (look at the links section).

    Script structure :

       1st two bytes : 82h 00h
          They seem to always have these values.

       3rd byte      : Start of the first script block.

    Script block structure :

       1st two bytes : Block type
          Type range from 0 to 10.
          (1=Object, 2=Code, 5=Strings, 8=Pointers to strings)

       2nd two bytes : Length of block
          Total block size, starting from the first byte

       5th byte      : Start of block data

Rem.: There's no index to the script blocks, the blocks are chained, you need to calculate their positions by starting with the first one, adding its length to the pointer, then reading the second one, etc.

You can look at my C++ program that display the code section of a script file :
scr_code.cpp
